Abstract

The present invention provides a pressure buffering device and an ink jet printer filter. The pressure buffering device includes a closed elastic housing with an elliptical cross-section. The closed elastic housing undergoes elastic deformation under the action of internal pressure, so that the cross-section of the closed elastic housing changes between an ellipse and a circle. Thus, a reasonable ratio of the major and minor axes of the ellipse can be calculated according to the pressure fluctuation range and the required volume change to be compensated. When the pressure of the external ink pipeline fluctuates, the closed elastic housing absorbs the flow impact caused by the pressure fluctuation through the reciprocating change trend of the housing shape between an ellipse and a circle, and has a good pressure buffering effect.
